Some further examples of applied green chemistry are supercritical water oxidation, on water reactions, and dry media reactions. Bioengineering is also seen as a promising technique for achieving green chemistry goals.
Solution : Bio-plastic or biodiesel is a product of green chemistry.
Definition of green chemistry Green chemistry applies across the life cycle of a chemical product, including its design, manufacture, use, and ultimate disposal. Green chemistry: Prevents pollution at the molecular level. Is a philosophy that applies to all areas of chemistry, not a single discipline of chemistry.
green chemistry, also called sustainable chemistry, an approach to chemistry that endeavours to prevent or reduce pollution. This discipline also strives to improve the yield efficiency of chemical products by modifying how chemicals are designed, manufactured, and used.
Reaction of methylamine and phosgene to produce MIC (methyl isocyanate) is not an example of green chemistry.
Answer. A suitable example of green chemistry is Bioplastics. Bioplastic is a substance that is based on organic biomass rather than petroleum.
Green solvents usually are used in the enzyme-assisted extraction methodology, which are the solvents with lowest toxicity such as acetone, ethanol, methanol, 2-propanol, ethyl acetate, isopropyl acetate, methyl ethyl ketone, 1-butanol, and tert-butanol [6].
Green chemistry synthesis couldalso involve the following. (i) Substitute CFCs by environmental friendly HFCs and other compounds. (ii) Replace halogenated solvent by liquid CO 2 for drycleaning.
Green chemistry is a branch of chemistry that is a design of chemical products, processed in such a way that it reduces or eliminates the generation of hazardous substances. It applies to the chemical reagents, reactions, products including its design, manufacturing, use, and disposal.
Paul Anastas and John C. Warner co-authored the groundbreaking book, Green Chemistry: Theory and Practice in 1998. The 12 Principles of Green Chemistry outlined within this work declared a philosophy that motivated academic and industrial scientists at the time and continues to guide the green chemistry movement.
Less chemical disruption of ecosystems. Less use of landfills, especially hazardous waste landfills....Human health:Cleaner air: Less release of hazardous chemicals to air leading to less damage to lungs.Cleaner water: less release of hazardous chemical wastes to water leading to cleaner drinking and recreational water.More items...
The idea of green chemistry was initially developed as a response to the Pollution Prevention Act of 1990, which declared that U.S. national policy should eliminate pollution by improved design (including cost-effective changes in products, processes, use of raw materials, and recycling) instead of treatment and ...
